How many of you own a Gingin Maru machine? I have one, and I really love it! The big chance music is the most rewarding thing to hear after lining up those 7s!

Does anyone want to discuss this machine?

I have a question?
Is there a challenge mode or an "F mode" hidden in the game? If so, what are the requirements to triggering it? I looked up the manual and did some translations, but did not find anything...
